Who would have thought that cane toads even have personality, let alone that it is apparently important to the species ability to adapt? Such a possibility causes one to consider the potential role that personality plays in the larger, evolutionary scheme of things. We know from experience that many other species have personality and that personality is of crucial importance in human social interactions.
The concept of personality is also important theologically. Christian theology across the board assumes and asserts that God is a person and has the marks of personality (loving, compassionate, cares about justice, is "slow to anger") exemplified for us in Christ. Trinitarian Christians believe that God is actually three persons (persona), Father, Son, and Holy Ghost. While professional theologians understand that the Latin term persona does not mean "person" in our English sense, the vast majority of English-speaking Christians translate the "personhood of God" as meaning God has personality. It can be argued that this idea that God is a person who has personality is but another case of us creating God in our own image, which has pretty much been my own personal view for a long time. It seems ludicrous on the face of it that the Divine Creator Beyond could in any sense have something as human and mundane as personality.
Still, it is worth considering that personality as a tool of our evolutionary development reflects a predisposition of the Creator, perhaps even an aspect of divine reality. It remains entirely speculative to assert the personality of God, but it is less speculative to claim that personality is somehow within the "providence of God" and again somehow compatible with "God's will for humanity." At the very least, it would seem that our having personalities is not a barrier that stand between us and God as such. Certainly, the way we express personality can be a barrier, but it is not inherently so.
If, then, we apply the English-language conception of person to God as a metaphor we are not asserting something necessarily illogical or out of sorts with modern science—so long as we remember that we are using personhood metaphorically. It functions thus as a helpful "mask" (the original Latin meaning of persona) of the Divine Beyond, which remains unknown to us directly. It is not wrong to think of God in personal terms including the ides of having a personal relationship with God. Whether or not God is a person or has personality, we can legitimately experience God in these terms—and think of God in this way. It is, we might say, in our God-given nature to do so.
